An electron neutrino is a tiny, nearly massless particle that is part of the family of neutrinos. It is produced during certain types of radioactive decay, such as in the process of beta decay, where a neutron transforms into a proton. Electron neutrinos interact very weakly with matter, making them difficult to detect, but they play a crucial role in understanding the universe and the fundamental forces of nature. These neutrinos are associated with the electron, one of the basic building blocks of matter. They are essential in the study of particle physics and help scientists explore the mysteries of the universe, including the processes that power stars like our Sun.
